Get to Know Me

What are some of the specific conditions you treat?

Hypertension, diabetes, hypothyroidism, preventive medicine, heart disease, well care.

What would you like patients to know about your approach to care?

I’m interested in providing individualized care for the patient that takes all of their health needs into consideration. I invite my patients to be involved in all decisions and to take responsibility for their health care choices. If we succeed in partnering together, we can achieve a long and healthy life.

We follow the most up to date guidelines in preventive care and screening medicine.

What inspired you to become a doctor?

As a grade school student, I enjoyed the sciences. In college, my father underwent cardiac surgery. His cardiologist inspired me to become a physician with his compassion for my father and our entire family during a difficult time. Thankfully, my father did well for some time. I had the privilege to be in this physician's class at the NYU School of Medicine, and I informed him of the impact he had on me.

Been his patient forever and I have confidence in him
I trust Dr. Wertentdeil with my health from every aspect. He is incredibly thorough, listens well, takes time to explain anything new, and I feel truly cares about his patients and their health. I have not always had that experience with other physicians (not Valley)
He is the best.
The doctor went through my medical profile and we discuss any concerns about my health
Dr. Wertenteil always listens to my issues, and gives direct honest feedback and guidance.
